The main attraction at Lassen Volcanic National Park is, you guessed it, Lassen Peak. It was dormant for almost 27,000 years until the unexpected happened. Believed to be extinct, the southernmost active volcano in the Cascade Range erupted without a warning on May 30, 1914. Nearly one year later, on May 22 at 4:30 p.m., the Great Explosion of this California volcano took place, blasting volcanic ash, rock fragments, and pumice into the air. As a result, the larger and deeper of the two craters—which we now see near the summit of the volcano—were formed.

While volcanoes are fascinating to learn about, the hazards they pose are a part of life for many Californians. Seismologists have found that there are at least seven active volcanoes around California. They may not physically show signs of activity, but that's typical for volcanoes. They lie dormant for years and suddenly erupt without warning. Fortunately, seismologists and other scientists ensure that they study these volcanoes to prepare Californians when the time comes.

Many eruptions happened 400,000 years ago until it became dormant about 18,000 years ago.

As always, the United States used the Salton Buttes to gather geothermal power that currently generates power for 325,000 homes. There isn't enough available data for seismologists to figure out the volcanic activity's pattern, but there's still a possibility of future eruptions.

The broad inconspicuous volcano in the center of the photo is Brushy Butte, a small shield volcano SSE of the Medicine Lake Highlands. The Brushy Butte complex has produced a broad apron of basaltic lava flows, seen here from Timbered Crater with the Big Valley Mountain fault scarp in the background. Fresh-looking flows extend preferentially down the regional gradient to the south as far as the Falls River valley, but the age of Brushy Butte is not well known. The volcano may be of late-Pleistocene or early Holocene age. (Photo: Lee Siebert, Smithsonian Institution)
